Description

Technical Field

[0001] This invention relates to the field of automated circuit board testing technology, and in particular to a testing device and testing equipment. Background Technology

[0002] Electronic components typically require testing before leaving the factory. For example, motherboards for mobile phones, tablets, and computers are usually tested using probes to improve yield. During testing, the probes press on test points on the motherboard to obtain the test value at that point. The test value is then compared with a set value to verify whether there are defects such as short circuits or open circuits at that point. This testing method is relatively simple and not conducive to the analysis and research of test data. Summary of the Invention

[0037] Reference Figure 1 and Figure 2 This invention provides a testing device for mounting an oscilloscope, which displays test results intuitively and clearly through waveforms, facilitating the analysis and research of test data. The testing device includes a base 100, a first testing module 200, and a second testing module 300. Both the first and second testing modules 200 are mounted on the base 100. The first testing module 200 includes a signal pin 210 and a first driving component 220. The signal pin 210 is connected to one of the oscilloscope's terminals. The first driving component 220 is connected to the signal pin 210 and drives the signal pin 210 to move, allowing the signal pin 210 to test different test points on the device under test. The second testing module 300 includes a grounding pin 310 and a second driving component 320. The grounding pin 310 is connected to the other terminal of the oscilloscope. The second driving component 320 is connected to the grounding pin 310 and drives the grounding pin 310 to move, allowing the grounding pin 310 to be aligned with different positions on the device under test.

[0038] During testing, the first driving component 220 drives the signal pin 210 to move according to the position of the test point on the device under test. The signal pin 210 anchors at the test position. At the same time, the grounding pin 310, located on the side of the signal pin 210, is driven by the second driving component 320 to anchor at a suitable position on the device under test. Since the signal pin 210 and the grounding pin 310 are respectively connected to the two terminals of the oscilloscope, the various electrical signals at the test point, such as voltage, current, and phase difference, are displayed on the oscilloscope in the form of waveforms. This makes it easy to observe the signal waveforms at different test points. Furthermore, the oscilloscope has various calculation functions, which can be used to obtain and display the signal difference waveforms at different test points, facilitating the analysis and study of the test data.

[0039] like Figure 2 As shown, the testing device also includes a positioning module 400, which is mounted on the base 100. The positioning module 400 is used to obtain the position of the Mark point (test point) on the test piece. The first driving component 220 drives the signal needle 210 to move according to the position of the Mark point to be tested, so that the signal needle 210 is stuck at the Mark point. The second driving component 320 selects a suitable position on the side of the Mark point and drives the grounding needle 310 to be stuck. The required waveform is obtained by the combination of the signal needle 210 and the grounding needle 310 being stuck.

[0040] Combination Figure 2 and Figure 6 The positioning module 400 includes a mounting bracket 410 connected to the bottom of the base 100. The positioning module 400 also includes a CCD camera 420 and a light source 430. The CCD camera 420 and the light source 430 are mounted on the side of the mounting bracket 410. The light source 430 is located below the CCD light source 430. The light emitted by the light source 430 illuminates the surface of the workpiece under test, which can improve the clarity of the CCD camera 420's image and improve the positioning accuracy of the Mark point. By taking pictures with the CCD camera 420, the coordinate position of the Mark point can be obtained, enabling the signal needle 210 to prick and test different Mark points.

[0041] The positioning module 400 also includes a lifting drive component 440, which is fixed to the mounting bracket 410. A CCD camera 420 and a light source 430 are mounted on the lifting drive component 440. The lifting drive component 440 drives the CCD camera 420 and the light source 430 to move up and down, adjusting the focus of the CCD camera 420 on the test piece and the brightness of the light source 430 illuminating the surface of the test piece. This allows the testing device to be suitable for testing test pieces with different testing accuracies. The lifting drive component 440 can be a cylinder, a ball screw, a micrometer, etc.

[0042] Combination Figure 1 and Figure 2The base 100 includes a base 110, a first mounting portion 120, and a second mounting portion 130. The first mounting portion 120 and the second mounting portion 130 are respectively connected to two sides of the base 110. These two sides can be adjacent or opposite sides. A first test module 200 is connected to the first mounting portion 120, and a second test module 300 is connected to the second mounting portion 130. This makes the first test module 200 and the second test module 300 independent of each other, avoiding motion interference, and making full use of the external space of the base 110, resulting in a more compact connection between the first test module 200 and the second test module 300. In addition, a mounting bracket 410 is fixed to the bottom of the base 100. After the positioning module 400 is installed on the mounting bracket 410, the positioning module 400 is located on the side of the first test module 200 and the second test module 300. On the one hand, the distribution of the positioning module 400 and the test modules is relatively compact; on the other hand, the test modules do not affect the field of view of the positioning module 400.

[0043] Furthermore, the first mounting portion 120 is inclined. Specifically, the upper end of the first mounting portion 120 is connected to the base 110, and the first mounting portion 120 as a whole is inclined away from the base 110. Setting the first mounting portion 120 in an inclined state facilitates the signal needle 210 to insert itself into the Mark point, and also facilitates different signal needles 210 to cooperate with each other to insert themselves into the same Mark point, while avoiding interference between the signal needles 210.

[0044] like Figure 3 As shown, the first drive assembly 220 includes a first drive member 221 and a guide rail 222. The guide rail 222 is fixed to the first mounting portion 120 and parallel to the extension plane of the first mounting portion 120. The signal needle 210 is slidably connected to the guide rail 222, which guides the movement of the signal needle 210. The first drive member 221 is connected to the signal needle 210 and drives the signal needle 210 to move. When it is necessary to strike the Mark point, the first drive member 221 drives the signal needle 210 to move, causing the signal needle 210 to descend and strike the Mark point, or the signal needle 210 to rise and move away from the Mark point. The first drive member 221 can be a linear motor, cylinder, electric cylinder, or other drive element.

[0045] The first drive assembly 220 also includes a grating ruler 223 and a reading head 224. The grating ruler 223 is mounted on the first mounting part 120. The reading head 224 is connected to the signal needle 210 and moves with the signal needle 210. The reading head 224 is slidably connected to the grating ruler 223 and can record and display the moving distance of the signal needle 210, so as to facilitate the observation and acquisition of the movement information of the signal needle 210.

[0046] The first test module 200 also includes an anti-collision component 230, which is fixed to the first mounting part 120. The anti-collision component 230 is used to provide a reverse support force to the signal needle 210 when the test device is powered off, so as to prevent the signal needle 210 from falling due to its own weight and hitting the test piece, causing damage or scrapping of the test piece. In one embodiment, the first test module 200 further includes a first mounting base 240, a signal needle 210 connected to one end of the first mounting base 240, the first mounting base 240 connected to a first driving member 221 and slidably connected to a guide rail 222, and driven by the first driving member 221 to move the signal needle 210 along the guide rail 222, a reading head 224 mounted on the first mounting base 240, and a supporting member 250 connected to the side of the first mounting base 240 near the anti-collision component 230; the anti-collision component 230 includes a movable sleeve 231 and an elastic member 232, the supporting member 250 is sleeved on the outside of the movable sleeve 231, and the end of the elastic member 232 abuts against the movable sleeve 231 and / or the supporting member 250. When the first driving member 221 drives the first mounting base 240 to move, the signal needle 210 moves up and down with the first mounting base 240. At the same time, the supporting member 250 moves relative to the moving sleeve 231. The elastic member 232 can be sleeved on the outside of the moving sleeve 231. When the supporting member 250 moves relative to the moving sleeve 231, the two ends of the elastic member 232 can support the moving sleeve 231 and the supporting member 250. Therefore, even if the signal needle 210 is discharged when the power is off, the supporting member 250 is supported by the elastic member 232, which can prevent the signal needle 210 from colliding with the test object. Alternatively, the two ends of the elastic member 232 are respectively connected to the bottom of the supporting member 250 and the bottom of the moving sleeve 231. When the signal needle 210 falls when the power is off, the elastic member 232 can also provide an upward elastic force to the supporting member 250 to buffer the falling speed of the signal needle 210.

[0047] In other embodiments, combined with Figure 3 and Figure 4 The anti-collision component 230 includes a power output rod 233, a movable sleeve 231, and an elastic member 232. The movable sleeve 231 is sleeved on the outside of the power output rod 233. The elastic member 232 is located between the movable sleeve 231 and the power output rod 233. The upper end of the elastic member 232 abuts against the movable sleeve 231. The abutting member 250 is sleeved on the outside of the movable sleeve 231. The lower part of the movable sleeve 231 has a step 2311.

[0048] Under normal conditions, both the power output rod 233 and the movable sleeve 231 are in the retracted state. The elastic element 232 is compressed due to the resistance of the movable sleeve 231 and the power output rod 233. When the first driving member 221 drives the first mounting base 240 to rise and fall, the supporting member 250 rises and falls relative to the movable sleeve 231. Under the power-off state, the pressing effect of the power output rod 233 and the movable sleeve 231 on the elastic element 232 disappears, the elastic element 232 rebounds, and the movable sleeve 231 is rebounded by the upward elastic force of the elastic element 232. The lower step 2311 of the movable sleeve 231 can hold the abutment 250. Even if the signal needle 210 falls due to its own weight, the first mounting base 240 stops falling under the abutment action of the movable sleeve 231 against the abutment 250, which can prevent the signal needle 210 from colliding with the test object. Furthermore, due to the elastic force of the elastic member 232, the movable sleeve 231 provides a certain buffering effect when it comes into contact with the abutment 250, avoiding a hard collision between the movable sleeve 231 and the abutment 250.

[0049] The power output rod 233 can be the output rod of a motor, a cylinder, or an electric cylinder. In one embodiment, the power output rod 233 is set as the output rod of a cylinder. Under normal conditions, the cylinder is filled with air, the power output rod 233 is in the retracted state, and it presses against the elastic member 232, causing the elastic member 232 to be in the contracted state. When the power and air are cut off, the pressing effect of the power output rod 233 on the elastic member 232 disappears, the elastic member 232 rebounds and pushes the power output rod 233 and the moving sleeve 231 to extend. The anti-collision assembly 230 also includes a power output rod 233 for mounting and a power body 234 for supplying power to the power output body. The bottom of the power output rod 233 is connected to the power body 234. The top of the power output rod 233 has a flange 2331. The movable sleeve 231 is fitted over the power output rod 233 and is tightly fitted or fixedly connected to the power output rod 233. The two ends of the elastic member 232 abut against the flange 2331 and the power body 234 respectively. Under normal conditions, the elastic member 232 is compressed by the flange 2331 and the power body 234. Under power-off conditions, the pressing effect of the power output rod 233 and the power body 234 on the elastic member 232 disappears, and the elastic member 232 rebounds, pushing out the power output rod 233 and the movable sleeve 231.

[0050] The power output rod 233 cooperates with the movable sleeve 231 to press the elastic element 232, so that the elastic element 232 is compressed in the normal state. When the power is off, the elastic element 232 rebounds and prevents the signal needle 210 from hitting the test object. In addition, in the normal state, when the holding member 250 moves relative to the movable sleeve 231, it does not need to overcome the elastic force of the elastic element 232, which helps to reduce the power of the first driving member 221 and reduce energy consumption.

[0051] The elastic element 232 can be selected as a sheet or a spring. For example, when the elastic element 232 is a spring, the elastic element 232 is sleeved on the outside of the power output rod 233.

[0052] like Figure 5 As shown, the second test module 300 includes a second mounting base 330, and the second drive assembly 320 includes a second drive member 321. The second drive member 321 is fixed to the second mounting base 330 and connected to the grounding pin 310. The second drive member 321 is used to drive the grounding pin 310 to rotate. The second drive member 321 can be a rotary motor, motor, etc. By driving the grounding pin 310 to rotate through the second drive member 321, the relative position of the grounding pin 310 on the test piece can be adjusted, making it easier for the grounding pin 310 to be anchored at a suitable position on the test piece.

[0053] In one embodiment, the second drive assembly 320 includes a drive belt 322 and two drive wheels 323. The drive belt 322 is wound around the surface of the drive wheels 323. One drive wheel 323 is connected to the second drive member 321 and is the active drive wheel 323. The other drive wheel 323 is connected to the grounding needle 310 and is the driven drive wheel 323. The second drive member 321 drives the drive wheel 323 connected to it to rotate, and drives the driven drive wheel 323 to rotate through the drive belt 322, thereby realizing the rotation of the grounding needle 310. The second drive assembly 320 also includes a rotating shaft 324 and a support arm 325. The rotating shaft 324 is connected to the driven transmission wheel 323 and is located at the bottom of the second mounting base 330. The rotating shaft 324 and the transmission wheel 323 are coaxially arranged. The support arm 325 is connected to the side of the rotating shaft 324 and protrudes radially toward the rotating shaft 324. The two ends of the support arm 325 are respectively connected to the rotating shaft 324 and the grounding needle 310. By setting the support arm 325, the rotation range of the grounding needle 310 can be expanded, making it easier for the grounding needle 310 to be anchored at a suitable position on the test piece.

[0054] The second test module 300 also includes a position detection component 340, which is mounted on the second mounting base 330. The position detection component 340 includes a detection element 341 and a sensing element 342. The detection element 341 is connected to the driven transmission wheel 323 and rotates with the transmission wheel 323. The sensing element 342 is fixed to the second mounting base 330 and is used to detect the position of the detection element 341. By detecting the position of the detection element 341 through the sensing element 342, the rotation angle and location of the grounding pin 310 can be obtained, facilitating the positioning of the grounding pin 310's anchor point. The sensing element 342 can be a photoelectric sensor, angle sensor, etc. The detection element 341 is connected to the side of the driven rotating wheel and protrudes radially toward the transmission wheel 323, so that the sensing element 342 can capture the position of the detection element 341. The detection element 341 can be a block-shaped or sheet-shaped component.

[0055] It should be noted that the second drive assembly 320 drives the grounding pin 310 through a combination of a transmission belt 322 and two transmission wheels 323. The two transmission wheels 323 can be connected to the second drive component 321 and the detection component 341 respectively, so that the position detection component 340 and part of the second drive assembly 320 can be installed on the second mounting base 330, which facilitates the layout of the internal components of the second test module 300 and simultaneously realizes the driving of the grounding pin 310 and position detection.

[0056] The second drive assembly 320 also includes a third drive member 326, which is fixed to the base 100 and connected to the second mounting base 330. The third drive member 326 is used to drive the second mounting base 330 to rise and fall. The grounding pin 310 is connected to the second mounting base 330 and rises and falls with the second mounting base 330, so that the grounding pin 310 can be grounded onto or detached from the test piece. Specifically, the third drive member 326 is fixed to the second mounting part 130 and is located on the side of the second mounting part 130 facing the positioning module 400. The second mounting base 330 is located on the side of the second mounting part 130 facing away from the positioning module 400, so as to make full use of the lower space of the base 110 and facilitate the layout of the internal components of the second test module 300.

[0057] The third driving component 326 can be selected as a cylinder, a motor, or a ball screw. In one embodiment, the third driving component 326 is selected as a rotary motor. The second driving assembly 320 also includes a synchronous belt 327 and two synchronous pulleys 328. The synchronous belt 327 is wound around the surfaces of the two synchronous pulleys 328. The synchronous pulleys 328 are rotatably connected to the second mounting portion 130. One of the synchronous pulleys 328 is connected to the third driving component 326. The third driving component 326 drives the two synchronous pulleys 328 to rotate, thereby causing the synchronous belt 327 to move around the synchronous pulleys 328. The second mounting base 330 is connected to the synchronous belt 327 and moves with the synchronous belt 327, thereby enabling the second mounting base 330 to drive the grounding needle 310 to rise and fall. Driving the second mounting base 330 to rise and fall by belt drive can improve the smoothness of the rise and fall of the second mounting base 330, allowing the grounding needle 310 to accurately strike the test piece.

[0058] It is conceivable that the two synchronous pulleys 328 are spaced apart vertically, and the synchronous belt 327 is wound around the synchronous pulleys 328, enabling the second mounting base 330 to move vertically. The second mounting base 330 can be connected to the synchronous belt 327 by means of threaded fastening, riveting, etc.

[0059] The present invention also provides a testing device, including at least one of the aforementioned testing devices, and further including a conveying device. The testing devices are mounted on the conveying device, which drives the testing devices to move in a horizontal plane. The conveying device can be a multi-axis module or a robotic arm. By mounting the testing devices on the conveying device, the testing devices can perform tests on different test pieces or different positions of the test pieces. Furthermore, the conveying device can drive different testing devices to move, allowing multiple testing devices to be combined to test different or the same mark point of the test piece. This enables the testing device to be compatible with different types of testing requirements and improves the testing efficiency of the testing device.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
